Paulustor, Graz, Renaissance city gate in Inner City district, Graz, Austria.

Paulustor is a three-story city gate in Graz's Inner City with round-arched passageways and a triumphal arch design. Substantial sandstone elements frame the eastern facade and make the structure stand out from nearby buildings.

The outer Paulustor was built from 1606 to 1614 by Hans Bertoletto as part of the new Paulustorvorstadt suburb; other sources give 1620 to 1625, with completion together with the third Sacktor. It replaced an inner gate in the medieval wall, whose "Stadtturm" was demolished in 1846/47. From 1823 to 1918 the gate served as a military prison, later being absorbed into the police barracks.

The Latin inscription beneath the two coats of arms runs line by line between the left and right cartouche, so the text must be read back and forth across the facade. It names Ferdinand and Maria Anna and states the gate was built to protect the homeland and keep both names in memory.

The building today houses regional government offices, so public access to the interior is limited. Visitors can best appreciate the gate's design by viewing the facade and portal from the outside to see the original 17th-century structure.

The Latin inscription beneath the two coats of arms zigzags line by line between the left and right cartouches. It names Ferdinand and Maria Anna and states the gate was built to protect the homeland and preserve their memory. The wrought-iron skylight grille above the portal dates from the construction period.
